Standard Sink Base Cabinet Sizes

When planning a kitchen remodel, it's important to understand the standard sizes of sink base cabinets. These cabinets are designed to accommodate a sink and provide storage space below. Knowing the standard sizes will help you plan your kitchen layout and choose the right cabinets for your needs.

Base Cabinet Sizes

Standard sink base cabinets come in a variety of widths to accommodate different sink sizes. The most common widths are:

18 inches

21 inches

24 inches

27 inches

30 inches

33 inches

36 inches

The height of sink base cabinets is typically 34 1/2 inches, while the depth is usually 24 inches. These dimensions are designed to fit standard sinks and provide ample storage space.

Sink Size Considerations

When choosing a sink base cabinet, it's important to consider the size of your sink. The cabinet should be wide enough to accommodate the sink, plus an additional 1 to 2 inches on each side for overhang. The depth of the cabinet should also be deep enough to accommodate the sink and any plumbing behind it.

Undermount Sinks

Undermount sinks are installed below the countertop, rather than on top of it. This creates a seamless look and makes it easier to clean around the sink. However, undermount sinks require a different type of sink base cabinet. The cabinet must have a solid bottom and a cutout for the sink. The cutout should be the same size as the sink, plus an additional 1/4 inch on all sides.

Overmount Sinks

Overmount sinks are installed on top of the countertop. This is a more traditional type of sink installation, and it is easier to install than an undermount sink. Overmount sinks require a sink base cabinet with a solid bottom and a cutout for the sink. The cutout should be the same size as the sink, plus an additional 1 inch on all sides.

Choosing the Right Cabinet

When choosing a sink base cabinet, it's important to consider the size of your sink, the type of sink you want to install, and the amount of storage space you need. By understanding the standard sizes of sink base cabinets, you can choose the right cabinet for your kitchen remodel.
